The conventional bicycle parking apparatus described above has the following problems.
(1) In order to enhance the fall prevention effect of the motorcycle, the inclination angle (gradient) of the entire wheel guide rail may be increased.
However, if the inclination angle of the entire wheel guide rail is increased, it is difficult for the conveying means to pull out the two-wheeled vehicle along the inclined wheel guide rail when leaving the vehicle. When it is forcibly pulled out, the wheel on the side that is not gripped rises and escapes from the wheel guide rail.
(2) As a method of pulling out the two-wheeled vehicle from the parking device in a state where the inclination angle (gradient) of the entire wheel guide rail is increased, the conveying means of the two-wheeled vehicle is improved so that the wheel on the passage side of the two-wheeled vehicle is extended in the direction of the wheel guide rail. Can be raised obliquely upward along
This method has a problem that not only the structure and operation control of the conveying means are complicated, but also the manufacturing cost is increased.
(3) For the reasons described in (1) and (2) above, the gradient of the wheel guide rail cannot actually be increased. Actually, the gradient of 1 ° to 2 ° with respect to the horizontal is the limit, and therefore, the fall prevention effect of the motorcycle could not be sufficiently exhibited.
(4) In the conventional bicycle parking device, the groove width of the parking groove is formed larger than the cross-sectional width of the wheel to ensure smooth running performance, and the groove bottom surface of the parking groove is used as the running surface of the motorcycle. Yes.
For this reason, a slight gap is formed between the wheel and the side surface of the parking groove, and this gap causes the wheel to fluctuate left and right when the motorcycle is taken in and out.
In particular, when the taking in / out speed of a two-wheeled vehicle is increased, severe lateral blurring occurs on the wheels and the steering wheel. Therefore, the taking in / out speed of the two-wheeled vehicle is suppressed to a low speed from the viewpoint of ensuring safety.
(5) As described above, since the speed of the two-wheeled vehicle to and from the bicycle parking device is kept low, there is not only room for improvement in the overall efficiency of the multi-story bicycle parking lot, but also a reduction in waiting time in units of one minute is desired. In the morning and evening commuting hours, users are forced to wait a long time.
(6) In the conventional bicycle parking device, the tire size (diameter and width) larger or smaller than the general size is excluded from parking because the stability of the motorcycle cannot be secured. In addition, heavy-duty, high-center-of-gravity power-assisted bicycles, which have recently become popular, are also excluded from parking.
Thus, conventional three-dimensional bicycle parking lots are limited to a small number of bicycles to be parked due to structural factors of the bicycle parking apparatus, and have not yet fundamentally solved the problem of neglected bicycles.

The present invention has been made in view of the above points, and an object thereof is to provide at least one of the following bicycle parking apparatuses.
(1) Realization of both improvement in speed of taking in and out of a motorcycle and prevention of falling of the motorcycle.
(2) Even if the wheel diameter and wheel width are different, or even a two-wheeled vehicle having a large weight and a high center of gravity, it can be parked, and the number of vehicles to be parked can be greatly increased.
(3) To be able to greatly contribute to the fundamental solution to the problem of neglected bicycles.

Transfers to the horizontal portion 32 of the wheel guide rail 31 and further proceeds straight from the horizontal portion 32 toward the inclined portion 33.

<3> Self-propelled Two-wheeled Vehicle FIG. 9 shows a state where the front wheel a1 of the two-wheeled vehicle A has reached the inclined portion 33 of the wheel guide rail 31.
When the front wheel a1 of the two-wheeled vehicle A reaches the inclined portion 33, the two-wheeled vehicle A changes from a horizontal posture to a forward leaning posture because of a difference in height between the front wheel a1 and the rear wheel a2.

When the front wheel a1 of the motorcycle A reaches the inclined portion 33 of the wheel guide rail 31 and the front end of the front wheel a1 reaches the intermediate gripping device 40, when the chuck mechanism 26 opens the rear wheel a2, the motorcycle A has its inertia. It runs on its own weight.
The front wheel a <b> 1 continues to travel along the inclined portion 33 of the wheel guide rail 31, and the rear wheel a <b> 2 passes through the guide rail 24 to the horizontal portion 32 of the wheel guide rail 31.

  In particular, regardless of the diameter and width of the front wheel a1, both sides of the tire run while contacting the pair of inclined surfaces 31b and 31b shown in FIG. 4, so the front wheel a1 goes straight without causing lateral blurring.

  Thus, even if the transport means 20 opens the two-wheeled vehicle A in the middle of warehousing, the two-wheeled vehicle A continues to move and keeps warehousing. It is possible to move to the operation, and the time can be shortened.

<4> Grasp of wheel by gripping device As shown in FIG. 2, the motorcycle A continues to run along the wheel guide rail 31 and the front wheel a1 is gripped by the intermediate gripping device 40 and the upper gripping device 50. The two-wheeled vehicle A stops self-propelled.
In the present invention, the front wheel a1 is gripped using the weight of the motorcycle A. Hereinafter, the gripping action of the front wheel a1 by the gripping elements 31, 40, 50 will be described in detail.

<4.1> Grasp of Wheel by Intermediate Gripping Device As shown in FIG. 7, the front wheel a <b> 1 that travels straight passes through the tip guide portions 41 a of the pair of gripping rods 41, 41 constituting the intermediate gripping device 40, and the opening width is A certain intermediate guide portion 41b is entered.

  The intermediate guide part 41b formed between the pair of gripping rods 41, 41 smoothly guides into the proximal end guide part 41c while preventing the front wheel a1 guided by the distal end guide part 41a from tilting.

The intermediate part of the front wheel a1 that has entered the opening of the proximal guide part 41c is crushed on both sides of the tire and firmly held.
The intermediate gripping device 40 can firmly grip the front wheel a1 even if the wheel diameter or the wheel cross-sectional width differs depending on the type of the motorcycle A.

<4.2> Grasp of wheel by upper gripping device As shown in FIG. 8, the minimum opening width L6 of the opening 52a of the gripping plate 52 constituting the upper gripping device 50 is the minimum width (maximum tire width) of an existing tire. ) It is formed smaller.
Therefore, when the front wheel a1 enters the opening 52a of the gripping plate 52, both sides of the tire are crushed by the inner surface of the opening 52a and the upper half of the front wheel a1 is gripped.
Similar to the intermediate gripping device 40, the upper gripping device 50 can grip the front wheel a1 even if the wheel diameter and the cross-sectional width of the wheel differ depending on the type of the motorcycle A.

<5> Reason why the gripping force of the tire increases The mechanism by which the wheel guide rail 31, the intermediate upper gripping device 40 and the upper gripping device 50 influence each other and grip the front wheel a1 firmly will be described based on FIG.

When the upper gripping device 50 grips the front wheel a <b> 1, the front wheel a <b> 1 is pressed downward as the gripping plate 52 rotates counterclockwise in FIG. 6 about the horizontal support shaft 51.
As a result, not only the lower part of the tire of the front wheel a1 is pushed into the back side of the opening of the parking groove 43 of the wheel guide rail 31, but also the upper half of the tire is pushed into the back side of the opening 52a of the grip plate 52. It is.
In particular, since the front wheel a1 comes in contact with the opening 52a of the single gripping plate 52 constituting the upper gripping device 50 in a form close to a point contact, the entry resistance is small, so the front wheel a1 is brought deep into the opening 52a. Can enter.

As the upper half of the tire is pushed into the back side of the opening 52 a of the gripping plate 52, the middle part of the tire is also pushed into the back side of the opening of the pair of gripping rods 41 constituting the intermediate gripping device 40.
Since the three grip elements 31, 40, and 50 can firmly grip the lower part, the middle part, and the upper half part of the front wheel a1, the tilting of the two-wheeled vehicle A to the side is completely restrained.

<6> Safety of the motorcycle during parking The bicycle parking device 30 according to the present invention is not only for preventing the tilting of the motorcycle A toward the side, but also for large shaking and vibration during an earthquake. Since it acts effectively, it has the characteristic that the safety of the two-wheeled vehicle A parked is higher.

<6.1> Tire gripping force increasing action In the conventional bicycle parking device, the tire gripping force does not increase even if the two-wheeled vehicle A shakes or vibrates due to an earthquake or the like, but the bicycle parking device according to the present invention At 30, the weight of the two-wheeled vehicle A acts in a direction that increases the gripping force of the front wheel a1, so the gripping force of the tire increases.

Specifically, in the present invention, the own weight of the two-wheeled vehicle A in the forward leaning posture is acting toward the vertical direction and the front wheel a1 side.
If the two-wheeled vehicle A is shaken or vibrated in this state, the opening 52a of the gripping plate 52 constituting the upper gripping device 50, the openings of the pair of gripping rods 41 constituting the intermediate gripping device 40, and the wheel guide rail 31 Since the front wheel a1 is pushed into the rear side with respect to the opening of the parking groove 43, the gripping force of the tire on the front wheel a1 is increased.

Similarly, the rear wheel a2 of the two-wheeled vehicle A is pushed into the rear side with respect to the opening of the parking groove 43 of the wheel guide rail 31 to increase the gripping force.
Thus, in the present invention, when shaking or vibration occurs, the gripping force of the front wheel a1 and the rear wheel a2 increases.

<6.2> Inhibition of Reversal Movement of Two-wheeled Vehicle As shown in FIG. 2, the two-wheeled vehicle A is parked on the parking device 30 in a forward leaning posture, and a part of its own weight is directed toward the front wheel a1. Is acting.
Therefore, even if an external force in the reverse direction acts on the two-wheeled vehicle A due to an earthquake or the like, a part of the weight of the two-wheeled vehicle A in the forward leaning posture opposes the external force, so that the two-wheeled vehicle A can be effectively prevented from moving backward.

<6.3> Self-weight return action of motorcycle A self-weight return action of the motorcycle A will be described with reference to FIG.
Even if the motorcycle A is slightly retracted on the parking device 30 due to a very large shake, if the front wheel a1 is positioned within the pair of gripping rods 41 constituting the intermediate gripping device 40, the intermediate guide portion 41b Prevents over-tilting of the front wheel a1.
When the backward movement of the two-wheeled vehicle A passes the peak, the two-wheeled vehicle A in the forward leaning posture self-propels, so that the front wheel a1 guided by the intermediate guide portion 41b is gripped again by the both gripping devices 40 and 50.

The length of the intermediate guide portion 41b may be determined in consideration of the backward movement distance of the motorcycle A.
Thus, even if the two-wheeled vehicle A moves backward on the bicycle parking device 30, not only can the two-wheeled vehicle A be prevented from falling and falling, but the two-wheeled vehicle A can be returned to its original correct parking position by its own weight.

<7> Reasons for forward-facing parking In general, when the motorcycle A that is parked falls, it often falls from the handle side.
This is because the center of gravity of the two-wheeled vehicle A is on the steering wheel side and the front wheel a1 is movable integrally with the steering wheel for steering.
In view of the cause of the fall of the motorcycle A described above, in this example, the bicycle A is parked forward with respect to the bicycle parking device 30.
If the motorcycle A is parked forward, not only can a plurality of positions of the front wheel a1 be gripped, but also the free movement of the handle integrated with the front wheel a1 can be reliably restrained, so that the motorcycle A is parked backwards. The effect of preventing the motorcycle A from falling is increased.

<8> Types of motorcycles that can be parked and the number of parked bicycles The wheel guide rails 31, the intermediate gripping device 40, and the upper gripping device 50 that constitute the parking device 30 have different opening diameters and different wheel cross-sectional widths. The two-wheeled vehicle A can be parked in a safe and stable posture.

  Furthermore, the lower part of the front wheel a1 and the rear wheel a2 of the two-wheeled vehicle A is gripped by the wheel guide rails 31, and the middle and upper half of the front wheel a1 are firmly gripped by the intermediate gripping device 40 and the upper gripping device 50, which are arranged in steps. Therefore, even if the two-wheeled vehicle A is a heavy-weight, high-centric electrically assisted bicycle, parking is possible.

In particular, the bicycle parking device 30 can park in a state of being almost vertical without the inclination toward the side of the motorcycle A.
Therefore, the arrangement interval of the bicycle parking device 30 can be set narrowly to the last dimension that does not interfere with the handle of the adjacent two-wheeled vehicle A, and the number of bicycles parked in the bicycle parking lot can be increased.

[Outgoing operation]
When the two-wheeled vehicle A is unloaded from the bicycle parking device 30, the operation is basically the reverse of the above-described loading operation. Hereinafter, the unloading operation of the motorcycle A will be described.

<1> Retraction of motorcycle The guide rail 24 of the transfer device 22 that constitutes the conveying means 20 is also located on the same horizontal line as the horizontal portion 32 of the wheel guide rail 31 of the parking device 30 when leaving the vehicle.

When leaving, the chuck mechanism 26 of the transfer device 22 shown in FIG. 9 moves horizontally and grips the rear wheel a2 of the two-wheeled vehicle A to be released, and then the chuck mechanism 26 moves backward. As a result, the motorcycle A is pulled out to the passage 11 side.
During this time, as shown in FIG. 4, since no gap is formed between the side surfaces of the front wheel a1 and the rear wheel a2 and the pair of inclined surfaces 31b, 31b constituting the parking groove 34 of the wheel guide rail 31, the motorcycle A Even if the vehicle moves backward at a high speed, the front wheel a1 and the rear wheel a2 go straight without causing lateral blurring.

Since the horizontal portion 32 constituting the wheel guide rail 31 is located on the same horizontal plane as the guide rail 24 of the transfer device 22, the rear wheel a <b> 2 mounted on the horizontal portion 32 can be obtained simply by the backward movement of the chuck mechanism 26. Can be smoothly transferred to the transfer device 22.
In particular, since the wheel guide rail 31 has the horizontal portion 32, the front wheel a <b> 1 does not escape from the guide groove 34 of the inclined portion 33 even when the two-wheeled vehicle A is moved at a high speed.

<2> Releasing the grip of the front wheel When the rear wheel a2 of the two-wheeled vehicle A is moved backward in the horizontal direction, the front wheel a1 located on the inclined portion 33 of the wheel guide rail 31 travels toward the horizontal portion 32.
Since the front wheel a1 shown in FIG. 9 moves in the widening direction of the openings of the wheel guide rail 31, the intermediate gripping device 40 and the upper gripping device 50 (leftward in FIG. 9), the gripping of the front wheel a1 is easily released. it can.

  As the front wheel a1 moves backward, the pair of gripping plates 52, 52 rotate in the opposite direction to that at the time of storage until the stopper pin 53 comes into contact with the side end surface of the extension mast 36 by the spring force of the spring 54 constituting the upper gripping device 50. Then, it returns to the initial standby position (FIG. 6).

<3> High-speed pullback of the two-wheeled vehicle When the front wheel a1 of the two-wheeled vehicle A reaches the horizontal portion 32 from the inclined portion 33 of the wheel guide rail 31, the two-wheeled vehicle A changes from the forward inclined posture to the horizontal posture.
Further, the front wheel a1 is transferred from the horizontal portion 32 of the wheel guide rail 31 to the guide rail 24 of the transfer device 22, whereby the mounting of the two-wheeled vehicle A on the transfer device 22 is completed.

When the front wheel a1 of the two-wheeled vehicle A travels on the inclined portion 33 and the horizontal portion 32 of the wheel guide rail 31, the front wheel a1 travels on the pair of inclined surfaces 31b and 31b inclined, so that the front wheel a1 does not move sideways. Due to the presence of 32, even if the two-wheeled vehicle A is moved at a high speed, the front wheel a <b> 1 can be prevented from being lifted from the guide groove 34 of the inclined portion 33, thereby preventing wheel removal.
Therefore, since the two-wheeled vehicle A can be pulled back from the bicycle parking device 30 to the transfer device 22 at a high speed, the operating efficiency of the loading and unloading of the entire bicycle parking lot is markedly coupled with the effect of shortening the time of the conveying means 20 at the time of loading. Get better.
